[libvirt] [PATCH 0/11 v2] Add supports for three new QMP events



v1 ~ v2:
   * Two more patches, [5/11] to prohibit tray='open' for
     block type disk. And [9/11] to introduce a new domain
     state 'pmsuspended'

   * Definition (including name) for DEVICE_TRAY_MOVED event
     is changed into:

     typedef void
     (*virConnectDomainEventTrayChangeCallback)(virConnectPtr conn,
                                                virDomainPtr dom,
                                                const char *devAlias,
                                                int reason,
                                                void *opaque);

   * Definition for both SUSPEND and WAKEUP event are changed,
     one more parameter 'int reason' for future extension.

   * While SUSPEND event is emitted, the running domain will be
     transfered into the new domain state "pmsuspended", instead
     of "paused". And while WAKEUP is emitted, it will transfer
     the domain state to running only if the domain state is
     "pmsuspended".
     
This patch series adds support for 3 new QMP events: WAKEUP,
SUSPEND, and DEVICE_TRAY_MOVED, and related changes on domain's
conf and status.

[1/11]
  Add support for tray moved event

[2/11] ~ [6/11]:
  New attribute "tray" is added to disk target, it indicates
the tray status of removable disk, i.e. CDROM and Floppy disks,
its value could be either of "open" or "closed", defaults to
"closed", and a removable disk with tray == "open" won't have
the source when domain is started.  The value of "tray" will
be updated while tray moved event is emitted from guest.
  tray status 'open' is prohibited for block type disk.
  Prior to these patches, if the user ejected the medium of
removable disk from guest side, and then do migration or
save/restoring, the guest will still starts the medium source
,and thus the medium will still exists in guest, which is
strange. These patches fix it.

[7/11] + [11/11]:
  Add support for wakeup event, and update the domain status
to running if the domain is in pmsuspended state, while the wakeup
event is emitted.

[9/11]
  Introduce new domain state "pmsuspended", which indicates the
domain has been suspended by guest power management, e.g, entered
into s3 state.

[8/11] + [10/11]:
  Add support for suspend event, and update the domain status
to pmsuspended if the domain was running, while the suspend event
is emitted.
